Improve gamut mapping of Color Management System by perceptual quality-oriented analysis

The state-of-the-art solution for Color Management System (CMS) proposed by ICC V4 is mainly based on color distribution. No sophisticated image content analysis is included. However, not all color points are viewed equal in perception, and they should be clustered into different groups according to their visual importance so that different mapping strategies can be applied respectively to achieve a better color image reproduction. The proposed work introduces the perceptual image quality concept into gamut mapping of Color Management System by a multi-domain image gamut analysis. The ambiguity of rendering intent selection can be alleviated by content-aware image gamut analysis whose intention is to realize an Image Gamut Boundary Reduction (IGBR). It enables CMS a more reasonable selection of rendering intents and more coherent reproduction.
